SOCKET FOR REMOVING TOOLS FROM OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 360,311, dated March29, 1887.

To all whom, it may concern:

Be it known that I, ARTHUR WILLIAM LEWIS, of Bradford, in the county ofMeKean and State of Pennsylvania, have invented certain new and usefulImprovements in the Manufacture of Sockets; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this specification.

My invention relates to an improvement in the method of manufacturingsockets for removing tools or obstructions from oil, gas, or Artesianwells; and it consists in a socket made from a tube in which the grainof the metal extends at right angles to the length of said tube, so asto form the socket with the grain of the metal extending around itscircumference, and having the pin or head welded to the socket, and theslips then attached to the tool thus formed, as will be more fullydescribed hereinafter.

The object of my invention is to simplify and cheapeu the constructionover the process heretofore employed for producing sockets by lesseningthe amount of metal used, doing away with all forging 011 the bowl andreins of said socket, and lessening the amount of lathe-work necessaryto finish and complete the tool, and thus produce a lighter and strongersocket.

Figures 1, 2, 8, 4, and 5 are views illustrating the old method ofmaking sockets for removing lost tools or obstructions from oil-wells.Fig. 6 is a view illustrating my method.

Heretofore in the manufacture of these sockets two reins, A, are drawnout from the bar-iron under the steanrhammer to the shape shown in Fig.1, and then these reins are welded together, as shown in Fig. 2, so asto form the upper part of the bowl of the socket, the grain of the metalrunning lengthwise of the reins and the part of the bowl, as shown. Tothe part thus formed the head or pin 13 is Application filed August 14,1886. Serial No.2l0,912.

welded, and to the upper part of the bowl are then butt-welded a numberof rings, 0, in which the grain of the metal runs around theircircumference. This socket thus produced has to be turned up and boredout in the lathe, milled, and the slips secured in place. Tools thusproduced are expensive, because the welding must all be done by hand,the parts are not exact, and consequently a large amount of lathe-workhas to be done to complete the tool. The bowl of the socket must beformed of welded rings, with the grain of the iron running around theircircumference, for the reason that as soon as the slips take hold of thearticle to be removed from the well they pull down in their seats andwedge between said article and the walls of the bowl of the socket, thushaving a tendency to split the socket open.

In forming my sockets I take a tube with the grain of the metalextending at an angle to its length, and of the right internal andexternal diameter for the bowl of the socket, and from this I cut therequired length. As the grain of the metal extends around the socket,.and not lengthwise of it, when the strain exerted in removing the toolcomes upon the socket, the tendency is to split the bowl. As the metalhas sufficient cohesion where the grain extends around the circumferenceof the socket to prevent all possibility of splitting, no rings arenecessary, and hence the socket is lighter, more easily constructed, andmuch cheaper than one constructed of forged castings having a series ofrings buttwelded upon them.

My socket being formed from a single thickness of metal, which is of thenecessary internal and external diameter, all necessity is done awaywith for handforging on the body, and with a great share of thelathe-work necessary to fit and finish a rough forging. Slots are cut inthe sides of the socket thus formed, so as to receive the slips used inthis couuec tiou.

In case it should not be desired to weld the pins or heads upon thesockets, the upper portion of the socket may be provided with a which isprovided with a head or pin and slots 10 female thread, and then the pinscrewed into to receive the slips, substantially as shown position. anddescribed.

Having thus described my invention, I In testimony whereof I affix mysignature in 5 claimpresence of two witnesses.
